Louise Thompson’s mystery date – which she described as ‘the night of her life’ – has been widely reported as One Direction star Niall Horan.

Last night’s episode of Made In Chelsea saw Louise, 22, get it in the neck from her castmates after it emerged she spent the night at an admirer’s home – jeopardising her blossoming relationship with co-star Andy Jordan in the process.

Louise’s other man, thought to be 19-year-old Niall, tried to woo her with his guitar-playing skills although she insisted she thought of her new hang-out buddy as nothing but a little brother, further suggesting the Kiss You singer could indeed be the unnamed lothario.

Recalling the drama last night, Andy said: ‘She goes for a drink. Four hours later I haven’t heard from her at all. I asked how was your date? Nothing. It gets to two in the morning. I text where are you? No reply.’

Adding fuel to the fire, it then emerged Louise never came home – but had found the time to snapchat their co-star Rosie Fortescue.

Confronting Louise later on, Andy said: ‘You said (to Rosie) I’m having the best time of my life, he’s playing guitar for me.’

Eventually realising her mistake, Louise told him: ‘I’m really sorry. The whole thing was really out of order and there’s nothing I can do about what’s happened.

I just want to get back to the happy relationship that we both have.’

‘I love you and I want to work through it,’ Andy replied.

Dishing the dirt on the goings on between Niall and Louise, a source revealed last month: ‘It started with jokey comments on Twitter, but now they text each other all the time.

‘They were on the phone last week when he suggested she go over and sent a car. It was secretive and exciting,’ the insider added to The Sun.
